Operational Dust Monitoring & Remedial Action Programme
Voyager II Quarry, BGC Plant Crushing & Screening
The Lakes, WA
1 INTRODUCTION
The environmental factor assessed by the Environmental Protection Authority (EPA) relevant
to this management plan is “dust”.
Management of dust is a key issue for all extractive industry operations. Whilst it is accepted
that some dust generation is unavoidable during most types of ground disturbing activity, it is
unacceptable for this dust to have health, environmental or significant amenity implications for
the surrounding community.
The following quarry operations have the potential to cause dust lift-off:
• Drilling and blasting;
• Loading, hauling, conveyor movements;
• Crushing and screening involving primary, secondary and tertiary crushing with
associated screening to various product specifications; and
• Trucking operations.
1.1 Legal Framework
Voyager Quarry was assessed under Part IV of the Environmental Protection Act 1986 (see
below). In addition to the updated Ministerial approval of the project (Statement 934 of April
2013) , the proponent will need to comply with a range of statutory and policy requirements as
outlined in Table 1 below.
The project, which was initially described within BGC’s Public Environmental Review (PER)
(URS 2003), was referred to the EPA on 19 December 2001 by the Commissioner for Soil and
Land Conservation.

The quarry is at Lot 14 (Figure 1), Horton Road, The Lakes, Shire of Northam that is owned by
BGC. In December 2001, the EPA determined the level of assessment for the proposal at
PER, and this level of assessment was subject to a two week appeals process. A number of
appeals against the level of assessment were considered by the Minister for the Environment
and dismissed on 1 May 2002. The subsequent PER document was released for public review
for a period of eight weeks from 6 January 2003, closing on 3 March 2003. An extension was
then provided to allow for further public submissions until April 2003. Following a review of the
submissions, BGC modified its proposal and incorporated details of additional monitoring
activities and data within its Response to Submissions (URS 2004).

2 THE PROJECT
The Voyager Quarry II is located at Lots11 and 14 Horton Road (Avon Location 1881), The
Lakes, Shire of Northam (Figure 1 & 2 indicate the project boundary).
The Voyager II quarry is for the extraction of a resource which is an extension of a Key
Extraction Area designated in the Western Australian Planning Commission’s Basic Raw
Materials Planning Policy.
Ministerial Statement 706 set conditions on the construction and operation of a new quarry
that was to replace the original Voyager Quarry, now nominated Voyager I. With expiry of the
licence agreement between BGC and the landowner, the Operating Licence L5356 for
crushing and screening at Voyager I was not renewed and was allowed to expire on 3rd
October 2010. The new quarry, nominated Voyager II, was commissioned on 24th September
2010 under operating licence L8415.
Further to submission by BGC under Section 46 of the EP Act in October 2010, Statement 872
was issued in August 2011 replacing condition 706:M6.1 with new condition that extends the
use of tertiary crushers to 19:00 hours on Saturdays. Further to this, under Section 46,
Ministerial Statement 934 was issued in April 2013.
The development of the quarry will ultimately require the clearing of 91.5 ha of vegetation over
the estimated 50 or-more-year life of the proposal. It is anticipated that the project’s
development will occur in six stages, with Stage 1 and Stage 2 being initially developed to
provide room for the new below ground level facilities and infrastructure. Subsequent stages 3
and 4 have now been completed as well. All infrastructure, crushing and screening plants will
be housed below ground level, and the site is surrounded by a buffer of trees and other
vegetation.
2.1 Receiving Environment
The receiving environment relating to the aspect of dust is the amenity and health of nearby
residents that could potentially be impacted by the proposed operations. Figure 2 indicates the
nearest residential locations that are potentially at risk from dust emissions.
The nearest residence to the proposed quarry site is a privately owned property in the Shire of
Mundaring, which will be approximately 560 m to the west of the operational area. Other
settlements are located to the north and east of the proposed quarry site (Figure 2).
2.2 Potential Environmental Impacts of the Project
Concerns were originally raised by residents about dust from all operational aspects of the
project. The potential for unacceptable off-site impacts from dust is most affected by the
prevailing wind direction during dry summer conditions when east to south easterly winds
prevail.
P a g e | 7
Operational Dust Monitoring BGC, The Lakes, July 2018
A large number of submissions were received on this particular issue during the publication of
the project in 2002. The majority of these pertained to the perception that the proponent’s old
Voyager I operations was performing poorly with respect to management of dust. Concerns
were also raised with respect to future operation of Voyager II and the potential impacts of
dust on nearby residents’ health, well-being and amenity.
3 PRINCIPAL ENVIRONMENTAL OBJECTIVES
3.1 BGC Objectives for Dust Management
The objective of the programme is to minimise and manage dust emissions that are directly
emanating from and leaving the site associated with all operations including land clearing,
excavations, blasting, stockpiles and general operational activities such as screening, crushing
and transport.
3.2 Proponent Commitments
The proponent provided the following objectives for the dust management plan. The objectives
are to ensure that:
• Nuisance dust levels are not experienced by neighbours and do not cause any health
problems;
• Dust generated during the operational phases of the quarry expansion does not
significantly impact on amenity;
The operational layout for the proposed quarry expansion will minimise dust and particulate
emissions from the quarry.
4 DUST CONTROL STRATEGIES IMPLEMENTED TO DATE
The quarry operator will have had considerable experience over more than 20 years in
managing dust issues in the old quarry; this experience has been applied and improvements
made, where required, at the relocated quarry. Consequently, this previous experience is
outlined below.
4.1 Potential Dust Sources in the Quarry Operations
The following quarry operations have the potential to cause dust emissions:
• Drilling and blasting;
• Materials movement – loading and unloading, conveyor transfer points;
P a g e | 8
Operational Dust Monitoring BGC, The Lakes, July 2018
• Materials processing – crushing and screening;
• Vehicle movement over unsealed ground;
• Vehicles leaving the premises with dust on chassis; and
• Vehicles leaving the premises without loads properly secured.
In the Voyager II quarry operation, BGC has modified its blasting practices to minimise the
potential for blast dust to reach residences and obtains a Monday To Friday (weekly) wind
direction prediction and quarry management set blasting for when wind conditions are
favourable.
It should be noted, however, that direct observations of wind conditions ( for example the wind
sock which is installed for that purpose) on the day of blasting and at the time of blasting, will
over-ride the decisions based on predicted wind direction. This will be the case for both,
unfavorable wind conditions (south easterlies) and favourable wind conditions. Final decisions
on whether to blast or not will be taken at the time when blasting is imminent.
Also, because regulations forbid explosives being left unattended in the ground when the
quarry is closed, they must be detonated on Friday afternoons regardless of wind conditions if
it has not been possible to detonate them earlier in the week.
This also is the case during storm events where lightning may be present, any explosives
which are in the ground are required to be detonated, by law. It is expected that such
circumstances may arise only on a few occasions each year.
When BGC responded to public submissions during the EIA process in 2002/03, the
proponent identified that a number of actions have been undertaken over the last few years to
improve dust management and other environmental issues at the old quarry. These
improvements which included the use of improved capital equipment, facilities and procedures
are outlined in Table 2.
Reports of inspections performed by the Department of Mining and Petroleum (DMP) at the
time for worker occupational health and safety purposes, note that dust management at the
site particularly that associated with material processing activities, was of a high standard.

Plan blasting according to weekly wind
predictions;
Delay blasting as late as possible until
conditions (winds) are favourable;
Delay blasting if wind conditions are not
favourable, however charges cannot be left
in the ground over a weekend and cannot be
delayed beyond Friday or if electrical storms
are likely.
BGC issued an internal memo for the revised
blasting instructions, including:
If wind directions are between east and
south of south east, then the blast must be
delayed until wind conditions are more
favourable. This should be checked
(confirmed) by the observation of the wind
sock, installed at the site for this purpose
prior to blasting.

5 DUST CONTROL STRATEGIES EMPLOYED AT THE QUARRY
5.1 Strategies Required
There are two separate quarry operations to be considered when planning dust management
strategies. These are
• Overburden removal: These are carried out close to surface wind conditions; special
precautions and planning are required for these operations.
• Quarrying operations that include those activities listed in Section 4.1 and dust
management strategies are required for each type of operation. However, the risk of dust
emissions crossing the proponent’s boundaries are less likely due to the depth of the
quarry operations being well below ambient wind conditions.
The above are further detailed in the sections below.
5.2 Overburden Removal
5.2.1 Proponent commitments
The following commitments have been previously provided by the proponent in regard to dust
management during overburden removal.
• Develop the quarry in a staged process so that possible impacts from overburden
removal are limited to five separate occasions over the life of the quarry.
• Undertake overburden removal only under favourable weather conditions – principally
during the wetter months or during north westerly winds
• Establish a phone link to the quarry manager for nearby residents.
• Keep residents informed of when activities are likely to occur.
• Control any large bare expanses of soil and overburden are left exposed over the dry
summer period.
• Ensure that dust control mechanisms (spray and tanker trucks) are implemented where
and when required.
• Undertake visual monitoring of dust at the boundary during these activities and stop
work if unfavourable wind conditions cause dust to lift-off in the direction of residences.
Action to be taken for the above commitments and additional dust control and management
measures are outlined in Tables 3, 4 and 7.

5.3 Quarrying Operations
5.3.1 Proponent commitments
The following actions have been implemented by the proponent in regard to dust management
for quarrying operations.
• Certain haul roads sealed with asphalt.
• Watering the haul roads.
• Watering of benches and pit floors.
• Watering of stockpiles.
• Watering of shot-rock in the pit before it is loaded and hauled to the crushing plant.
• Using wet drilling practices for the quarrying operations.
• Using water sprays throughout the plant and at transfer points.
• Watering and covering loads when transporting material off-site.
• Road sweeper on sealed roads
• Implementing speed restrictions within the quarry.
• Enclosure of the primary crusher.
• Fogger system installed in primary crusher.
• Sprinkler system.
Quarry operational and dust management strategies, and improvements already implemented,
have been carried forward into the new operations.

6 WEATHER INFORMATION REQUIRED
Information required to ensure the best possible outcomes for dust management includes:
• Maintaining an automatic weather station for monitoring wind data;
• Reviewing modelled wind forecasts for current and five-day (Monday to Friday) long-term
weather information;
• Maintaining ambient dust monitoring equipment, in two locations at boundaries adjacent to
nearby residents, most likely to provide upwind and downwind suspended dust
comparisons and live weather information;
• Visual monitoring of dust emissions. Observations of the wind direction via the wind sock
will take precedence over predicted (computer modelled) wind direction prediction.
6.1 Weather monitoring requirements
Where there is the potential for dust lift-off, in order of importance, dust impacts on amenity
are primarily influenced by:
• wind strength;
• wind direction; and
• ground level moisture.
As ground-level moisture is to be artificially controlled by spraying, the key parameters for
managing the effectiveness of dust suppression and management are wind strength and wind
direction.
For quarry planning purposes long-range weather forecasts are obtained on a weekly basis to
ensure that adequate planning is in place for conditions likely to cause dust emissions. This
information is followed up on daily basis by monitoring real-time data available from the
dedicated weather station and direct observations of the wind sock.
The Quarry Operator must be aware when hot, dry and windy conditions are likely to occur
and appropriate action should be taken in deploying water sprays on the day, before such
conditions arise so as to prevent dust emissions or to avoid operations that would be most
likely to cause excessive dust emissions.
6.1.1 Wind Direction and strength
The York Weather Station is located approximately 45 km east of the project area. Table 5
below provides Bureau of Meteorology average dominant 9 am and 3 pm wind directions
P a g e | 17
Operational Dust Monitoring BGC, The Lakes, July 2018
derived from Bureau of Meteorology weather station at York collected between 1957 and
2014.
Wind roses were down-loaded from:
http://www.bom.gov.au/climate/averages/wind/selection_map.shtml
Table 5. Dominant wind directions for York Weather Station derived from BoM seasonal
wind roses.
Season 9am 3pm
Winter West to North West to North
Spring East to South South West to North West
Summer South East East to South East and West
Autumn East to South West and East (more variable)
The information in Table 5 suggests that placing dust monitoring equipment on a north-
west/south-east axis would enable both up-wind and down-wind dust data to be obtained
under the most common weather conditions, especially during summer when the risk of dust
emissions is highest due to strong desiccating east to south easterly winds.
6.1.2 Weather forecasting information
Modelled wind directions are obtained from Stass Environmental for The Lakes locality
(Quarry location). The modelled data is site specific for The Lakes region, with a resolution of
8 km. This information is obtained every Monday morning; and provides a table of wind data
for the following 5 days.
The best possible wind strength and wind direction forecasts can be obtained for at least five
days ahead using the Stass Environmental modelling. On the basis of this information, blasting
is not conducted when wind conditions are south easterly and gusting. Note that blasting has
to be undertaken, regardless of wind direction and speed, at times when an electrical storm is
forecast, or on Friday afternoons (explosives cannot be left in the ground over the weekend).
7 DUST MONITORING REQUIREMENTS
The monitoring requirements are derived from using conditions imposed by the DWER on
similar activities in the near Perth area (Heavy Industrial) and the DWER licence conditions.
Heavy Industrial EPA Policy and Regulations have been relied on from the Kwinana
Environmental Protection Policy (EPP) Area A of 1999 and 2005.
The following monitoring requirements are required:
P a g e | 18
Operational Dust Monitoring BGC, The Lakes, July 2018
BGC undertakes a dust monitoring programme for the purpose of determining off-site dust
impact from the operation. The programme incorporates the following:
i. TEOM and BAM dust monitors shall be installed in accordance with the Australian
Standard 3580;
ii. The dust monitors, referred to above (i) are installed at the locations as depicted in
Figure 2;
iii. PM10 is monitored using the dust monitors referred to above as per Australian
Standard 3580;
iv. PM10 is measured and recorded for the purpose of obtaining a 24 hour average; and
v. Monitors are installed to ensure wind direction, wind speed and temperature is
measured and recorded as per Australian Standard 2923.
vi. Wind sock for visual operational management.
BGC ensures that the dust monitors and wind data monitors referred to in the above section
(i), are maintained and calibrated in accordance with the manufacturer's specifications and
Australian Standard 3580.
8 RELEVANT STANDARDS
The following relevant standards apply to the measurement of atmospheric particulates are
summarised in Table 6 below.

Operational Dust Monitoring BGC, The Lakes, July 2018
8.1 Performance criteria
The following are indicators for tracking the progress in managing and controlling dust
emissions.
8.1.1 Visual monitoring
Visual monitoring of dust emissions will be the first line of action for dust management,
particularly during overburden removal. Actions may be instigated without delay at the
observed source of dust emission. In the case of overburden removal this would include
ceasing the offending operation, application of water sprays and only restarting operation at a
low intensity and slowly increased to ensure dust emissions are minimised. In the case of
quarry operations, the application of corrective water sprays at the offending operation would
be appropriate.
8.1.2 Short-term corrective monitoring
A short-term “corrective action” dust concentration target is recommended to assist in
maintaining ambient standards. Should the target concentration of PM10 particulates be
exceeded, this would initiate management procedures as for Section 9 to ensure that ambient
dust standards are met. The dust monitors are configured to send an email message to the
appointed staff, notifying of the exceedance.
8.1.3 Complaints register
A complaints register will be maintained to verify that operating parameters are effective.
The complaints register will track any problems that are likely to occur in regard to visual
amenity.
When completing the Annual Report, the Quarry Manager will indicate any remedial action that
has been taken in regard to complaints received.
8.2 Ongoing Monitoring
Table 7 below provides all dust monitoring activities required to minimise the risk of dust
emissions crossing the boundaries of Lot 11 and 14.
